Abstract
A surgical nail (1), in particular, an intramedullary nail, has a central axis (2) and is formed of a material (M) having a modulus of elasticity (E). A plurality of transversal openings (5) run transversally to the central axis (2) and have a cross-sectional profile (F) and a transversal axis (6), the cross-sectional profile (F) having a maximum length (a) that runs in the direction of the central axis and a maximum width (b) that runs perpendicular to the length. A longitudinal bore (3) runs coaxially with the central axis (2) and defines a wall (4). A longitudinal insert (7) can be introduced into the region of the transversal opening (5) via the longitudinal bore (3). Said insert has a longitudinal axis (13) and consists of a material (m). The insert (7) comprises at least one longitudinal slot (25) so that said insert can be elastically compressed in a radial manner and includes a plurality of radial elevations (14) fitting inside the transversal openings (5).
